2 Claims.

lThis invention relates to roll wringer mechanism, more particularly to means for releasing pressure between wringer rolls, and has for itsl principal object provision of mechanism for acl complishing such release by means of movement of the wringer frame with respect to its supporting post. l Y

Another object is to provide a wringer frame pivotally mounted upon a post structure and mechanism kco-operative between the post and wringer whereby pivotal movement of the wringer brings about release of the roll pressure mechanism.

An-additional objectflies in the provision of a wringer frame pivotally mounted upon a post structure, operable upon pivotal movement to release pressure'between the wringer rolls, the

same having in combination a co-operative mech-V anism adapted to assist said pivotal movement.

Another object is to provide a wringer roll mechanism pivotally mounted upon a post structure, operable upon pivotal movement to release pressure between the wringer rolls, the same having in combination a co-operative manually operative mechanism adapted to bring about said pivotal movement.

A `further object -is-toprovide a simple and inexpensive mechanism forl releasing roll pres- Sure in a. quick and easy manner.

Other objects will appear in the following description and accompanying drawing in which:

Fig; 1 isa side-elevational view of a wringer embodying my invention wherein that portion comprising thevinvention is shown in section to facilitate description; .Y f Fig. 2 is a fragmental plan view showing details of parts to be described;

Fig. 3 is a view similar to Fig. 2, showing certain parts in operated position as will be described and Fig. 4 is a fragmental side elevational view showing details of structure with certain parts in operated position to be described.

Fig. 1 discloses my device as combined with a conventional roll wringer mechanism which includes a wringer frame I I having upstanding end portions I2 and I3, upper and lower rolls I4 and I5, ,a releasable top frame I6, and a spring I1 supported in the top frame adapted to apply resilient pressure upon the upper roll I4 to force the same downwardly upon lower roll I5 to hold the rolls in pressure relation.

The lower roll has driving connection with a power source, not shown, through a flexible coupling I8, a gear I9 and a gear and clutch mech- (Cl. 68-32) y l anism roperated by a revolving 3 shaft 20. The drive Vmechanism is thought suiciently 1 wel known to obviate detailed description. Y e

Upright I2 Aincludes a bracket portion 2l having extending upper and lower portions 22 which Sli are pivotally supported on `the wringer post str-uc-V ture 23 by means of screws 24 whereby the-wringer frame maybe pivotally moved upon the post as indicatedA -in- Fig. v3. Thee-flexible coupling I8- permits such movement without alteration of the 1U- roll drive connection. f

Secured to the upper4 side-of the wringer post is a bracket member 25 which hasran extending portion 26, best shown in Fig. 4, and uponzithe end of this is secured an upstanding-Iug 21. Y

Lug 21is movably received in a-recessed portion of a member 28, whichispivotally mounted atf29-upon end memberr I2. n, Y Member 28 has outwardlyextending. portions 30 for a purpose to be described shortly. i Y k 20 `Referring to ther top frame I6, it will Ybe noted that at its right hand end, Fig. 1, it is releasably attached to uprightfl 3 by meansof a conventional hook arrangement 3|, andat its left hand end by means of a latch member,32 engagedin .an

opening 33 in the top frame. M

vLatch 32 is movably disposed inside ofv upright I2 by means of .a resilient supportV member 34 secured at 35 to upright I2.v .Y The support member has anopening 36 of suicient propor- 30 tions to clearV the pivotal mechanism of member 28 and member 34 is thus adapted to lie adjacent the wall of upright12, as shown in Fig. 1, with hook 32 engaged. in opening 33of the top frame. v YWith parts .in this positionthe rtop frame is ob- 35 viously retained Vupon uprights I2 and I3 in posi.- tion to render spring` I1v effective to hold vthe rolls` in pressure. relation. ',The relative position of partsl;` 28, and'34..is}clear1yshown in. Fig- 2. Fig'. '3 illustratesrelative v n1`cn`7einents"ofthe 40 several parts when the wringer frame is moved upon its pivotal bearings 24-24, wherein the lug 21 remains stationary while the pivotal support 29 of member 28 moves with the wringer frame and thus brings about rotation of member 28 45 whereby one of the portions 30 engage and move the latch support member 34 backwardly to withdraw latch 32 from opening 23 whereupon the top frame is released from upright I3. When released, the top frame moves upwardly, as in Fig. 4, 50 to relax spring I1 and remove pressure between the rolls.

Fig. 2 will illustrate that when the wringer rests in suitable alignment with its support, theY two side portions of member 34 are adapted to lie 55 2?" Y W Y 2,054,135

' evenly against the two projections 30 of the mem- Y ber 28.

Itfwill be obvious that the pressure of .member 34 applied in this manner is adapted to hold- 'member 28 in alignment and that the recess of member 28, engaging lug Y2'! provides a means :for'holding the wringer in suitable YalignmentV with its support. Y Y. Movement of thewringer frame inra direction opposite that shown' in Fig. 3 will Aobviously operate member 28fin an opposite manner to bring about the same result. i

' The foregoingy has described a release mecha= nism similar to that shown in my co-pending application No.7751,809.

VThe following will describe a cor-operative mechanism adapted to be used `Vin Vcombination with that just described, to increase the"u`tility y thereof.

Upon the post structure 23 is a stud 40 upon"V whichris pivtally mountedra member 4I having Yarm portions 42`Vexte'nlding outwardlyV upon both Y. sides of the wringer rolls.

Y wringer rolls as shown in Fig. 2, are in Yposition fMember 4Ifhas acentralextending portion 43` having va downwardly directed' stud 44 engaging in an extension of a recessV theV latter being that also engaging lug 21.

rOperation of member 28 to'release the VWringer rolls has already been described.' -It is thought bvious that arm portions 42,' lying alongside the convenient for Ymanipulatienby an operator, and

that manipulation into Vthe'p'osition'shownin Fig.V 3 will operate member 28,' with stud 21 as a iul-V crum,gto move the wringer out ofitsnormal alignmentV whereby release ofY the roll tensioning mechanism is accomplished.Y Y Y V*In connection with; this invention it is to be particularly noted that movement of the wringer Y to release thejrolls may, land would usually be,

brought about ,through Vmovements which are instructive'on the partk of van operator.

f During practical'use should anY operatorsy fingers berrcaught'between the rolls, initial instinc-Y Y tive'mov'ement would be to pull away and this Y movement would Vobviously@cause,Ythe pivotal movement'described A'to release the rollpressure.

' There a'furthermanual movement which may be' instinctive on the'part of many operators .whenfan accident occurs, and this must be con-jV sidered in connection with safety release-mechanisms. "Y k f Y.

For: example, if an Yoperators ngers become caught in the rolls, 'the/first. instinctive movement would perhaps be topull away4 as aboveV noted,however, it may be that simultaneously or .very soon afterthe initial pull the operator would y.place the other hand on some partv of the mechanism to push the body away, or to assist in resisting the feed-in movement of the engaged ngers.

It will be noted that arms 42 are placed in position to be most convenient When the operatorY makes a more or less involuntary movement to push against something with Vthe free hand as above stated. Y

Obviously the instinctive movements of an operator positioned at the top side in Fig. 3 would Vinclude pulling the engaged hand to swing the VwringerV into releasing position as shown, and

Vpushing against arm 42, toward the position shown to indirectly bring about an identical releasing action.

It is thought apparent that pulling the wringer vjmechanismjfor pushing arm 42Y will' bring Vabout Y Either 'mechanism oprelease of the v vringer. eratedsepa'rately will bringrabout the same result and when both mechanisms are operated'si-Y I multaneously'they co-operate to bring abouta like result.

ModincatiQns' of the structure and functions" herein described are obviously possibleY without alteration of the principle disclosed. I do not wishV to be limited in structure or principle exceptY within the scope of the appendedclaims.`
